Are polar amino acids hydrophobic or hydrophilic?
Hydrophilic
Are non-polar amino acids hydrophobic or hydrophilic?
Hydrophobic
Which amino acids have hydroxyl groups that can be phosphorylated which causes them to become negatively charged?
Ser, Thr, and Tyr
Which amino acid can create a disulfide bond with itself?
Cys
What is special about Pro?
its R group connects to the amine group which restricts rotation around the alpha carbon-amine bond
often appears in a turn of a beta sheet
What is the start codon? Which amino acid does it code for?
AUG - codes for Methionine
